Given the following boxplot where m is the median value, what statement could be made about the distribution of the data?Explain your answer.2. The Colorado State Legislature wants to estimate the length of time it takes a resident of Colorado to earn a bachelors degree from a state college or university. A random sample was taken of 265 recentin-state graduates.a) Identify the variable.b)Is the variable quantitative or qualitative?c)What is the implied population?3.

And we know that for skewed data the median is the best measure to describe the location. So here the median would be best measure of position.Top quartile means top 25% of the data. Here the total number of mice are 40 so top quartile consists of (40*25%) = 10 mice. Now 40% of them survived so (10*40%) = 4 mice survived.The percentile would give us what percent of the mice are in that category. So in this example it will pin point the information we are looking for.The quartile is somewhat similar to percentile. The percentile divides the whole group into 100 equal parts and the quartiles into 4 equal parts. So quartiles would give the 25 percentiles information.The standard score will give us the relative measures. It will give enough information to compare to different scores by standardizing them.
